  • Patent number: 10411340
    Abstract: A mounting arrangement and an antenna mounting device for mounting a directional antenna to fixed infrastructure. The antenna mounting device comprises a first adjustment element comprising a first end, an infrastructure part for attaching the antenna mounting device to the fixed infrastructure, and an antenna attachment part for attaching the directional antenna to the antenna mounting device. Moreover, the first adjustment element is coupled to the infrastructure part and to the antenna attachment part, and configured to adjust a first orientation of the antenna attachment part relative to an orientation of the infrastructure part, to provide adjustment in a first direction of the directional antenna. Furthermore, the first end of the first adjustment element is configured to remain at a fixed position relative to the infrastructure part, independently of the relative orientation of the infrastructure and the antenna attachment part.

  • Patent number: 9899716
    Abstract: It is provided a waveguide E-plane band-pass filter comprising a tubular, electrically conductive waveguide body. An electrically conductive foil is arranged in the waveguide body and extending along a longitudinal direction of the waveguide body, the foil comprising a plurality of resonator openings. Furthermore, the waveguide body comprises at least one ridge protruding from an inner wall of the waveguide body and extending longitudinally along the longitudinal direction of the waveguide body. The foil is in mechanical contact with said at least one ridge and arranged to divide an inner volume of the waveguide body into two portions. It is also provided a diplexer, a radio transceiver, and a method for filtering a signal using such a filter.

  • Patent number: 8553428
    Abstract: A component for mounting on a PCB, intended to support an electronics component, with an extension in the longitudinal, lateral and vertical directions. The component has a first and a second main surface, the second main surface being intended for mounting on the PCB. The component is made in a non conducting material, with a first layer of conducting material arranged on its first main surface, the conducting layer being connected to a conducting layer on the second main surface of the component by electrically conducting means. The component's extension in the vertical direction is smaller than its extension in either the longitudinal or lateral direction.

  • Patent number: 6900384
    Abstract: The invention relates to a cover (200,300,400,500,600) for an electronic device (100), which electronic device comprises a substrate (110) and at least two electronic components (120,130), one of which generates an electromagnetic field around itself, where the cover has a first main surface (210) that faces towards the electronic device, comprises a material that conducts current, and is designed and arranged in such a way in relation to the electronic components that a cooling medium can pass from the first (120) to the second (130) electronic component. The invention is characterized in that, by virtue of its shape and its material content, the cover has been given an increased ability to absorb at least part of the electromagnetic field that is generated by at least one of the electronic components.

  • Patent number: 4915043
    Abstract: A device for folding an edge of a fabric for making a single or a double hem. The device includes a pair of cooperating endless, driven bands for conveying the fabric edge through the device. One of the bands cooperates with a fixed rule and is twisted to correspond to the gradual folding of the fabric edge. The speed of one of the bands can be temporarily varied relative to the other so that the trailing edge of the hem is located somewhat inside of an edge of the fabric which extends transversely to the hem.
